An Overview of Various Techniques to Improve Receive Diversity in MIMO OFDM
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 10, Issue 6
Abstract
MIMO-OFDM system has been currently recognized as one of the most competitive technology for 4G mobile wireless systems. Techniques such as use of multiple antennas can be utilized in order to obtain a multiplexing gain, a diversity gain, or an antenna gain, thus enhancing the throughput (in terms of capacity) or bit rate, the error performance, or the signal-to-noise ratio of wireless systems, respectively. In this paper various receive combing techniques such as MRC, EGC and SC for enhancement of diversity have been discussed. Receive combining techniques with LDPC codes enhance the performance of overall system by providing coding gain. Overview of Alamouti’s STBC along with maximum likelihood (ML) decoding algorithms also discussed.
